Basic Electrical Troubleshooting - Short to Ground finding trick on the white rust magnet 

yes i have one of those power probes. brilliant bit of kit well worth the investment. great video too Chris

Great little tip, going to be using it for my home toolkit myself now

Top Video as ever cheers Chris

The Power Probe is well worth the money!!!

Chris i must say you`ve made my experience as a Land Rover owner (`96 300tdi Disco 1) here in Grenada West Indies a lot less horrifying! I`ve been able to do almost everything on my truck by myself with the help of your very informative and detailed videos, which build confidence and motivates people like myself who have little or in some cases no knowledge of the mechanical workings of a vehicle. So far i`ve done quite a bit as far as the cooling system, head gasket, EGR blanking, valve adjustments etc. however now im having some electrical issues blowing fuses for the indicator switch. I`ve tried swapping out the switch for two different ones from some freelanders that were in a scrap yard but problem still exists. As a matter of fact the fuse blows when the switch is not even installed and as soon as i turn on the ignition. I don`t have a probe but i do have a fluke multimeter. Any suggestions or methods i should use in order to figure out what the problem might be.(should i remove the fuse box/panel and check it for shorts) ??

I wondered, what special tool the white rust magnet woulb be..... it took me until seeing the Discovery before the coin dropped *lol*

BTW, thank you for doing these videos. I'm in Los Angeles, and unfortunately, I'm not at all mechanically inclined but I'd like to be somewhat self-sufficient. I appreciate your straightforward approach to teaching these tasks. I purchased my '95 RRC about six months ago, and while the original owner cared for it well for a long time, the intermittent owner was pretty awful to the truck for about 18 months. Trying to figure out what that guy did to the electrical systems... So thanks again for this tutorial.

so when you go wiggle wire harness and find the short does the bulb dim or go out completely as ive watched twi vids and both had light dim when found and other the bulb went out,i couldnt figure out why the bulb would go out because wouldnt this create a series circuit thus dimming both bulbs (pretend its a headlight circuit) as they now share the same circuit?

*So , Put a bulb to light by getting the power of where the fuse keeps blowing, Then wiggle wires around until lights either flicker or turn off and if it dims or turns off your around the short circuit?*

Where is the switch for an 02 sensor? Would that be in the ECM/PCM?

Beware car run 5 volts through some systems make sure you know what your powering up before you put 12 volts down

I use a door buzzer from a another car that way you don't have look but listen for buzzer. Great demonstration for those who don't know.

Hello would this method of the home made light be safe to do on the airbag fuse or would it risk deploying?

I made something similar to that tester many years ago, a useful device, so useful I think it got stolen 😢

I would not have thought of that, but so simple and effective. Thank you.

Great timing my right hand rear lights and number plate not working time to have a go

I have the old power probe got it many years ago off my snap on dealer. Think im over due for upgrade.

It looks like a very interesting tool, Chris

Again...another school day. Cheers Mate. As always worthwhile to watch your vids.

I'm going to get one of these.

It is so sad when someone thinks they are clear with their explanation......and your using pictures. Keep your day job, your not a good teacher.
